If you are buying a home with a mortgage, one of the first questions that comes up is what kind of survey your bank or mortgage lender needs. It is a common source of confusion, especially for first-time buyers, because lenders, estate agents and surveyors often use the same words to mean different things.
At Price Lilford, we carry out residential property surveys across Kent. This guide explains what your lender actually needs, what the bank’s surveyor does (and doesn’t) check, and how to choose the right survey to protect yourself.
Do mortgage lenders require a survey?
No. Most mortgage lenders only require a mortgage valuation, not a survey. The valuation is carried out by a surveyor acting for the lender, and its purpose is to confirm the property is worth enough to secure the loan. It does not tell you about the condition of the building.
That means a lender will usually approve your mortgage without anyone inspecting the property on your behalf. Whether you commission your own survey is up to you, but it is the only way to find out about defects, repair costs and future problems before you commit.
When a lender will ask for more
Sometimes the bank’s surveyor spots something during the valuation that the lender wants investigated before it will release the mortgage. Common examples include:
- Signs of damp or timber decay, where the lender may ask for a specialist damp and timber report
- Cracking or movement, which can lead to a request for a structural engineer’s report
- Non-standard construction, such as some concrete, steel or timber-framed homes
- Japanese knotweed on or near the property
- Concerns about concrete roofs or panels, which may need a RAAC inspection
- Spray foam insulation in the roof, which some lenders now treat with caution
In some cases the lender will offer the mortgage but hold back part of the money, known as a retention, until specific repairs are completed.
Cash buyers and remortgages
If you are buying with cash, there is no lender and no mortgage valuation, so nobody inspects the property unless you arrange it. If you are remortgaging, many lenders use a desktop or automated valuation instead of sending a surveyor at all.
What does the bank’s surveyor actually do?
The bank surveyor, sometimes called the lender’s valuer, is a surveyor appointed by your mortgage lender, often through a panel of approved firms. Even though you usually pay the valuation fee, the surveyor works for the lender, not for you. You don’t get to choose who carries it out, and their report is written for the lender’s benefit.
A mortgage valuation visit typically takes 15 to 30 minutes. The bank’s surveyor will:
- Confirm the property exists and matches the details in the mortgage application
- Assess its market value against comparable sales in the area
- Consider whether it would be easy to sell if the lender had to repossess it
- Flag any obvious, serious issues that could affect the value
The valuation does not include:
- A roof inspection or loft access
- Checks on structural integrity
- Damp, rot or subsidence assessments
- Advice on repairs or repair cost estimates
Many buyers never see the full valuation report. Some lenders share a copy, others simply confirm the figure and whether the mortgage can go ahead. Either way, it is not a record of the property’s condition, and it is easy to mistake it for a proper survey and discover problems only after moving in.
What if the bank’s valuation comes in low?
If the bank’s surveyor values the property below the agreed price, known as a down valuation, the lender will usually only lend against the lower figure. Your options are to renegotiate the price with the seller, increase your deposit to cover the gap, ask the lender to reconsider with evidence of comparable sales, or apply to a different lender. An independent survey can also help you understand whether the lower figure reflects genuine issues with the property.
Bank surveyor vs independent surveyor
| Bank’s surveyor (mortgage valuation) | Your own surveyor (RICS survey) | |
|---|---|---|
| Who they work for | The lender | You |
| Main purpose | Confirm the property is suitable security for the loan | Report on the condition of the property |
| Time on site | Usually 15 to 30 minutes | Several hours, depending on the property and survey level |
| Defects and repairs | Only obvious issues affecting value | Detailed findings with advice on what to do next |
| Who sees the report | The lender, and sometimes you | You |
Which survey should you get as a buyer?
Your lender only needs a valuation, but we strongly recommend commissioning your own survey so you know exactly what you are buying. The right level depends on the age, type and condition of the property.
RICS Level 2 Home Survey (Homebuyer Report)
The most popular choice for conventional properties in reasonable condition. It includes:
- A visual inspection of all accessible areas
- An assessment of damp, timber and structural movement
- Condition ratings for each element (green, amber or red)
- Advice on urgent repairs and further investigations
- An optional market valuation and insurance rebuild cost
A Level 2 survey is well suited to flats, bungalows, standard construction houses built from around 1900 onwards, and homes that haven’t been extensively altered. For most buyers it offers the best balance of detail and cost. Find out more about our residential surveys in Canterbury and across Kent.
RICS Level 3 Building Survey (Full Structural Survey)
The most detailed inspection available. It includes everything in a Level 2 survey, plus:
- In-depth analysis of the structure and construction
- Detailed explanations of defects and their likely causes
- Guidance on repair options and timescales
- Photographic evidence
- Clear recommendations for next steps
A Level 3 survey is the right choice for older properties (pre-1900), listed or historic buildings, large or unusual homes, renovation projects and properties with visible defects. If you are buying a property with potential problems, a building survey can save you thousands in unexpected repairs after completion.
Valuations in your own name
The lender’s valuation belongs to the lender. If you need a valuation for your own purposes, for example to challenge a down valuation, for probate or for shared ownership, it needs to be carried out by an RICS Registered Valuer instructed by you. Talk to us and we’ll advise on the right route for your situation.
Why your own survey matters
Avoid expensive surprises. Hidden problems such as damp, rot or structural movement can cost thousands to put right, and none of them are checked by the bank’s surveyor.
Renegotiate the price. If your survey highlights defects, you can use the findings to negotiate a reduction or ask the seller to carry out repairs before completion.
Walk away with confidence. If the problems are too extensive, a survey gives you the evidence you need to withdraw before you are committed.
Feel fully informed. Buying a home is stressful. Knowing the condition of the property gives you clarity and peace of mind.
The short answer
Your bank or mortgage lender needs a mortgage valuation, carried out by the lender’s own surveyor. It confirms the property’s value, not its condition.
For your own protection, you should consider an RICS Level 2 Home Survey for most conventional homes, or an RICS Level 3 Building Survey for older, altered or more complex properties.

Frequently asked questions
Do mortgage lenders require a survey?
No. Most mortgage lenders only require a mortgage valuation, which confirms the property is worth enough to secure the loan. A survey that reports on the condition of the property is optional, but strongly recommended.
What does a bank surveyor check?
The bank’s surveyor checks that the property matches the mortgage application, assesses its market value against comparable sales and considers how easily it could be resold. They only flag obvious, serious issues that affect value. They do not inspect the roof, loft, structure or damp in detail.
Can I see the bank surveyor’s report?
It depends on the lender. Some share a copy of the valuation report, while others only confirm the valuation figure and whether the mortgage can proceed. Because the report is written for the lender, it is not a substitute for your own survey.
Is a mortgage valuation enough when buying a house?
A mortgage valuation is enough for the lender, but it does not protect you as the buyer. It will not tell you about defects, repair costs or future problems. An RICS Level 2 or Level 3 survey gives you that information before you commit.
What happens if the bank’s valuation is lower than the asking price?
This is called a down valuation. The lender will usually only lend against the lower figure, so you can renegotiate with the seller, increase your deposit, ask the lender to reconsider with evidence of comparable sales, or apply to another lender.
